Synonym: Gasflood Recovery = Gasflooding

Motivation = maintain formation pressure at sweep interface with gas in case of high water mobility  $//<![CDATA[ \begin{array}{l}\frac{k_{rw}}{\mu_w} \gg \frac{k_{ro}}{\mu_o}\end{array} //]]>$ makes waterflood inefficient.

where  $//<![CDATA[ \begin{array}{l}s_{wi}\end{array} //]]>$ – initial water in oil pay,  $//<![CDATA[ \begin{array}{l}s_{org}\end{array} //]]>$ – residual oil to gas sweep.
